Description

FIELD OF THE INVENTION The present invention relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and extreme ranges. BACKGROUND OF THE INVENTION All shooters, whether they are police officers, soldiers, Olympic shooters, sportswomen and sportsmen, hunters, plinkers or weekend enthusiasts have one common goal: hitting their target accurately and consistently. Accuracy and consistency in shooting depend largely on the skill of the shooter and the construction of the firearm and projectile. The accuracy of a firearm can be enhanced by the use of precisely-made components, including precisely-made ammunition, firearm components and target acquisition devices. It is well known in shooting that using ammunition in which the propellant weight and type, bullet weight and dimensions, and cartridge dimensions are held within very strict limits...

AI Technical Summary

Benefits of technology

The present invention provides reticles that provide means for selecting secondary aiming points that accurately target an intended target at any desired range, including extreme distances. In particular, the reticles of the present invention provide markings or other indications that allow a user, for example, to associate a first aiming point of the reticle with an int

Problems solved by technology

At very long ranges, in excess of 500 yards, however, the skill of the shooter and the consistency of the ammunition is often not enough to insure that the shooter will hit the target.

In addition, conventional telescopic target acquisition devices are not generally useful at long ranges in excess of 400-800 yards.

At close ranges less than 100 yards conventional target acquisition devices generally fall short when extreme accuracy is desired.

Modifications to this basic system have not, thus far, enabled a skilled shooter firing at long ranges to acquire and hit a target quickly and reliably, regardless of the weapon used (assuming always that the firearm is capable of reaching a target at the desired long range).

Apparently because of the innate variation in the height of any given individual from that used to produce the reticle, and the resulting inaccuracy which that would produce at long ranges, Critchett's scope was only useful to 600 yards.

However, like Critchett, the usefulness of Rubbert for shooting other targets of varying size at long range is doubtful.

Leatherwood's scope, like the others discussed above, has
